Title: Method and apparatus for inspecting appearance of watermelon
Inventor: KAWAMICHI KENICHI
IPC: B65G43/08
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for inspecting the appearance of a watermelon using its stripe pattern. SOLUTION: An image of a watermelon is picked up with its stripes arranged in the vertical direction, and the image obtained is binarized, and the external form of the watermelon is taken out, and the center of a circumscribing rectangle cicumscribing this watermelon is found. A tilt correcting apparatus 6a draws a straight line passing this center at each constant angle, and finds an angle of a straight line whose watermelon-crossing-part length is the smallest. A stripe tilt measuring apparatus 6b rotates the watermelon by this angle and obtains a image of the erected watermelon, binarizes and takes out a stripe of the image of this erected watermelon, and finds a tilt angle of the stripe from the secondary moment of the stripe. A grade measuring apparatus 6c judges the grade of the shape of the watermelon by the tilt angle of this stripe.

Title: Electrostatic powder coating device
Inventor: SUZAKI KOICHIRO
IPC: B05B5/08
Filed: 1993-05-17
Abstract: PURPOSE:To efficiently coat a material with the bottom face not to be coated and to reduce the deposition loss by setting a conductive material on the surface of an endless belt conveying the material and electrically grounding the conductive material positioned close to and below an electrostatic powder coating gun. CONSTITUTION:A brake pad A, e.g. conductive, is placed on an insulating endless belt 2 with the bottom face abutted on a conductive material 3. When the pad A conveyed by this belt conveyor reaches a position close to and below an electrostatic powder coating gun 7, the material 3 is grounded, and hence the pad A is grounded. A charged coating powder 14 is then sprayed on the pad A from the gun 7, hence an attractive force is generated in the pad A by the mirror image effect of the Coulomb force of the electric charge of the powder 14, and the powder is electrostatically deposited on the upper and side faces to form a coating film. An attractive force is not generated around the belt 2. The material 3 is formed in the width smaller than that of the bottom face of the pad A, hence the exposed area is reduced, and the amt. of the powder 14 deposited on the belt 2 is smaller than before.
